The researchers manually inspected thousands of recently recovered AVCS and IDCS images from 1964, 1966, and 1969-70 and placed points along visible ice edges to help delineate North and South Pole sea ice extent.

Ice edge points from 9 September, 1969 overlaid on IDCS source image. Colors indicate confidence and whether the point is an edge, lead, or region of broken ice.

The relative size of the continent outlines has been corrected in these images. The new files are available for download as of 19 December 2013, so if you downloaded these files prior to this date, please obtain the corrected data via:

Note that the correction applies to the North and South Polar projections for all dates in the data set. The equatorial projection files were correct and have not changed. If you have any questions about the data correction, please contact NSIDC User Services at nsidc@nsidc.org.

Funded by NASA, NSIDC researchers enhanced these brightness temperatures from the 1960s with a correction that significantly minimizes seemingly random alignment errors in the original data that caused cloud edges and land features to appear jagged. The data are available as HDF5 formatted files.
